Answer, will mark brainliest darrell is trying to remove a nail from a board using the claw of a hammer, but the nail is stuck. which of the following could darrell do to make the job easier? a: use a hammer with a shorter handle. b: use a hammer with a longer handle. c: use a heavier hammer. d: use a hammer with a sharper claw.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
